Product Description:

Kollmorgen manufactures the H22NRHT-LNF-NS-00 in its H Hybrid Motors series. This is a two-phase stepper motor used to index or hold mechanical loads in packaging, printing, and pick-and-place machines. By advancing discrete rotor positions in response to drive pulses, it delivers controlled incremental motion without a feedback device and simplifies motion control in mid-torque automation axes. The motor follows the NEMA mounting convention, allowing direct installation in many existing drive frames and couplings.

Its mechanical envelope is categorized as NEMA 23, giving a square flange that mates with standard 1.86-inch pilot holes, while the round stator body measures 2.25 in. in diameter. Each electrical step advances the shaft by 1.8 degrees, so a full revolution consists of 200 discrete positions. At each target position, the motor holds within ±1.5% of the commanded angle, which is suitable for repetitive indexing stations. Two rotor stacks increase detent torque, and a laminated rotor improves flux linkage for higher low-speed torque. The motor uses a regular lead set with four parallel leads exiting the housing, and it does not include a feedback device.

Electrical characteristics and ambient limits support use in general factory conditions. The windings use Class B, 130 °C insulation, and the design operates in ambient temperatures from -20 °C to +40 °C. Inter-winding resistance to leakage is rated at 100 Megohms, while the insulation system can withstand up to 340 Vdc during dielectric testing. Heat generated by the winding is dissipated through the standard laminated construction, and the motor has a smooth shaft without a shaft seal. The motor uses standard construction and a four-lead parallel connection style that matches typical bipolar step drives.
